Would also check the flex hose between regulator and the black iron pipe.

Take the trailer out of the picture. Disconnect the rubber hose on the tongue right at the iron pipe and put the manometer on the end of the hose. Does the 2 minute drop happen indicating something on the tongue?

All good stuff above, but I have found 2 problems.

1- regulator to tank connector was loose! I had found it loose before and retightened (hand tight). This time I moved the "c" ring and moved the plastic hand wheel out of the way so I could get to the nut and put a wrench on it.

2- Ordered one of those gas sniffers and been hunting the leak. That took a while: turned gas on, went round and round, inside and out for over an hour, nothing! Left the gas on for 2 more hours... tester went off like a rocket inside the furnace housing outside after removing the cover! Went inside to confirm the furnace was off, it was.

Now I need to figure out how to test the furnace system. I want to make sure the thermostat is actually turning off the furnace and it is not a bad thermostat. Then check to make sure the valve is closing the way it should (I think this will be the problem).

STILL, I don't see how the furnace valve being stuck open would cause the propane alarm to go off when going 60mph down the highway. Scratch that, 10mph start/stop traffic congestion.

It has gone off 3 times, once the last night of a week long camp in February, next in that start/stop traffic, then most recently when having the fridge cooling down the day before leaving for a short boondocking experiment.

So this where I am now, troubleshooting the furnace system.

TTYL, Phil

I think it's going to be the valve, but 1st this video

Edit: more like it opens when not being told.
NOT Valve, control...

Check for continuity (voltage?) across the 2 blue wires before and after water column drop. And battery voltage across red/yellow.

Edit again: that's strange, even without the control board plugged in I detected gas in the exhaust port. Hmmm...
